I just got the July issue of Access Mag. On Pg19 KNOW-IT-ALL, It says DIRECTV'S DOUBLEPLAY. It says to press the down arrow to start storing up to 90 min. of live TV on each of your HDDVR's 2 tuners. Then press the down arrow to switch between the tuners. Well I tried it, but it does not work. Hopefully SOON?
